From d89cc617b954aff4030fce178f7d86f59aaf713d Mon Sep 17 00:00:00 2001 From: Takuya Yoshikawa Date: Wed, 1 Aug 2012 18:03:28 +0900 Subject: KVM: Push rmap into kvm_arch_memory_slot Two reasons: - x86 can integrate rmap and rmap_pde and remove heuristics in __gfn_to_rmap(). - Some architectures do not need rmap. Since rmap is one of the most memory consuming stuff in KVM, ppc'd better restrict the allocation to Book3S HV.
